To all whom it may concern:

Be it known that we, EARLE M. Glaser: and CHARLES W. STAPLES, citizensot tl e United States,- residingat Washburn, in the 5 county of Aroostook and State of Maine,

have invented contain new and useful lm-' be combined with a machine already in usewithout requiring any extended change in its structural arrangement, and in the use of 2 which the foot .of the driver may be employed for controlling the throttle independent ofthe hand throttle, or vice versa, there being no interference between the operation-of the two throttle members.

ment of this character which will permit the removal or replacing of the foot boards without necessitating the detachment or positioning of nuts, cotter pins, bolts, or other fastenings, whereby access to the throttle may be obtained in a ready and convenient manner.

With the above and other objects in view, as will appear as the nature of the invention is better understood, the same consists in the novel features of construction and arrangement of parts of a foot throttle or accelerator for automobiles, as will be hereinafter fully described and claimed.

In the accompanying drawings forming a part of this s ecification, and in which like characters )0 reference designate correspending parts; the figure is a view in per-j.

spective of the attachment.

Referring to the drawings, 1 designate an ordinary hand throttle rod, one, end of.

which is, connected with the throttle lever 2 of an ordinary throttle valve 3, this end of the rod havin connected with it one end oi. a coiled 'sprmg a, the other end of which is connected with the side of the car frame. At the end of the rod 1 opposite that carry-' ing the spring a is secured the usual hand throttle rod attachment 5, nuts 6 screwed on the adjacentend of the rod 1 serving to :adjust the-lengthof the latter, and also to A further object is to provide an attach-- act as a stop to give proper leverage to the attachment 5. v v

Secured to the red 1,-in any -preferredmanner, is a clip 'Z' through which loosely projects one end of a rod 8,.the other end which is bent at an angle, and terminates in a flattened head 9. The angle rod 8 at its bond 10 is pivoted between a two-armed bracket 11 secured to the under side .e'fthe foot-board F, the connection between the bracket and thelever being effected 'by a; bolt 12. The head 9 is desi ed to be engaged by the foot bracket peiil ofthe automobile, so that it is always undertbe centrol of the operator,

In operation, pressure on the head 8 causes the rod 8. to swingon the bolt 12, thereby imparting a swinging movement to the free end of the rod or that projecting through the clip 7 and imparts; asidewise' movement of the throttle 1 thereby to, shift the throttle rod lever 2 andefiect opening of the throttle, the spring 4 operating, auto matically to closev the: throttle when pressure is removed from the \head, 9. As the rod 8 is free to slide within the" clip .7 and is not held against endwisew movementyrelative thereto by a cotter pin, nut, or the like, foot-board F may readily be removed when occasion requires, to gain access to the engine or the like. By the connection of the hand throttle rod or lever already on the car with the attachment 5, and by the movement of the hand throttle on the steering wheel, the throttle rod .1 may be moved manually thus opening the throttle valve, and when the hand throttle on the steering wheel is released, the spring t will automatically close the th ttle valve. It will thus be obvious that the )footthrottle may be used independent of the hand throttle, and vice versa, the arrangement being such that there will be no interference betweem the two. 4 This foot throttle or accelerator gives a steady throttle when the throttle valve is closed, open, or partially opened, because the spring 4, by being attached to the throttle rod 1 and the car fram, holds the throttle rod steadily against the adjacent nuts 6'.

' To adapt this attachment to the throttle will require no extra parts or attachments on the carbnreter, as the original throttle rod is apertured lug,

moved to operate the throttle actuating,

cheap movable foot board, and an operating mem ber mounted upon the foot board having engagement with the throttle actuating member, said members being detached from engagement with each other upon the removal of the foot board and operating member.

2. In a motor vehicle, a throttle actuating member, a rod connected with one end of the member, a clip secured to the rod adjacent its other end, said clip having a laterally disposed lug, a foot board, a bell crank lever pivotally-connected to the under side of thei'oot board, said lever having one arm thereof slidablydisposed through said whereby said lug will be member, and whereby the arm of the bell crank lever may be disengaged from the red by the removal of the foot board together with the bell crank lever.

3. In a motor vehicle, a throttle actuating'member, a rod connected at one end to said member, a clip secured, to the rod adjacent its other end and having a laterally portion of the rod disposed apertured lug, a removable foot board, a bell crank lever pivotally mounted upon the under side of the foot board, said lever constituting aupedal, one arm of the lever being of uniform diameter toward its extremity, said extremity passing through and being slidably disposed in the aperture ofthe lug whereby the rod may be shifted on actuation of the bell crank lever and said lever may be disengaged from the rod upon the removal'of the foot board with the bell crank lever.

i. In a motor vehicle, the combination with a throttle valve operating element comprising a longitudinally shiftable rod, of a clip loosely embracing the rod. at one end and adapted to be connected to hand operated means for longitudinally shifting the rod, a stop upon the extremity of the rod and adjacent to the clip, and with which vsaidclip is adapted to engage to shift the rod, a clip mounted upon the intermediate and through which the rod is freely shiftable, a lever movable in a plane parallel tn the length of the rod and passing loosely through said clip, and a spring acting to retract the rod.

in testimony whereof we hereunto aflix our signatures in the presence of two witnesses.
